?Impact on Sleep and Importance of Good Sleep Hygiene

Bruxism is closely related to sleep quality. Disrupted sleep can exacerbate bruxism, and bruxism can, in turn, lead to sleep disturbances. Good sleep hygiene practices, such as maintaining a regular sleep schedule, creating a restful sleep environment, and managing stress, are essential for reducing the severity of bruxism and improving overall health.

Conclusion

Bruxism is a multifaceted condition requiring a comprehensive approach to management, involving behavioral, dental, pharmacological, and lifestyle interventions. Understanding its relationship with sleep and maintaining good sleep hygiene are crucial in managing this condition effectively.
